I just finished my b18c swap in my eg hatch with no major issues. I have 2 questions... -What should I be idling at? I seem to be at 900-1000 rpm's for idle. this seems ok, but it used to idle around 600 with the d15, and my old em1 was around 500. -Where should I be hitting vtec? I havn't taken it to 5500 yet because I am breaking in a new clutch, but at 4500, the exhaust tone changes and gets alot louder (like in vtec). Im just wondering if thid is vtec hitting early, or my IAB's activating?
